Naturaiiy this contem lates the use ofa fine granular coffee which dissolves and instantly mixeswhen subst'antihl iv boiling Water is introduced. i

It is the object of the presentiriv'ention to pro' vide a': coffeemahi'ng aeviee wherein the coffee is made immediately pa e to its being dispensed.

It is the object or this invention to proviae in such a device a cofiee measuring means which is manually rotatable t deliver a predet rmined quality dry Coffee into a; mixing cllalmbe'f'.

It is the further Object 6f this iriVfibibn t6 provide a valve construction governing in-Ie't of coffee, and a successive inlet of water into" said mixing chamber, as well as" a successive discharge of the mixed come in response to manual control;

Theu'pper end of bin 21 terminates in a cyl'itndrfoal upright portion within which'bin cover 2 is rem'ovabiy inserted. i

Cofiee measuring disc 25* is centrally carried at the end of indicating shaft 26' which is sliciabiy positioned through bushing 21 on cover 24;! and is adapted to visibi-y project up through opening 28 in container cover 12. Disc 25' rests upon the top of the coffee stored m bin II and is adapted to gravitate towards the bottom of bin 21' as the Coffee is used, with its upper visible end'indicating: the extent of the coffeesupply.

Thehollow converging portion 20 of casting i5 terminates in a dry coffee discharge: opening 29 which is adapted for registt y the measuring receptacle; 30 carriedon the outersurface of retatable drum 31. Said receptacle is removaihly secured within a corresponding opening formed in druma'l' by means of screws 32. It is contemplated that said receptacle may be; replaceflt by similar receptacles of varying capacity depending upon the quantity of coffee ori other substance sought to be measured. 7

Drum 31' is rotatabiy mounted within: oyhndrt caiportion 33 of casting l5, and upon the central operating shaft 36. Said. drumis' secured to'ishaft 34 by set screw 35, while said shatt is rotat'aieiy joumaled at one end Within the homow" huh 36 of thewciaims hereforming part of cover 38. The latter is removably secured to drum housing 33 by screws 38.

Sprocket gear 46 mounted on the end of shaft 84 is adapted to efiect rotation thereof in view of the sprocket chain 41 joined thereto and whose movement will be hereafter described. A secondary sprocket gear 42 is also carried on shaft 34 for rotatably operating the cup valve hereafter described.

Drum housing 33 has a discharge opening at its bottom which terminated in the hollow dry coffee chute 43 formed within casting l5. The lower end of chute 43 is adapted to discharge into coffee mixing chamber housing 44 also forming a part of casting l5. Said housing has a coffee outlet 45 in its bottom into which is threaded nipple 46.

Spigot housing 41 mounted on the front wall of container H and secured thereon by bolts 48 projects partially into the interior thereof. fluid passage 49 terminates in the downwardly projecting spout 50 while its inlet is joined to the nipple 46 by means of the interconnecting fitting Manually rotatable shaft 52 projects through housing 41 and carries a cylindrical valve member 53 which has a transverse opening 54 therein adapted for registry with thefluid channel in said housing. Member 54 essentially does not function as a valve, but merely provides a means of connecting between manually rotatable handle 55 and shaft 52, and at the same time permits fluid to flow through passage 49. The discharge of fluid through spout 56 is governed by the proper positioning of the cup valve in mixing chamber 44, hereafter described in detail.

It is seen from Fig. 3 that rotatable shaft 52 is journaled near its outer end through the bearing support 56 which extends upwardly from platform l4. Spur gear 51 and sprocket gear 58 are carried on the outer end of shaft 52 for rotation therewith, there being a suitable spacer 59' interposed between said gears. It will be noted that sprocket gears 58 and are interconnected by sprocket chain 4| for movement in unison.

Rotary shaft 59 extends centrally through mixing chamber 44, is journaled at one end within hub 66, and at points intermediate its ends within rotatable disc valve operating sleeve 6|. Said sleeve is rotatable upon and in respect to shaft 59, and is also journaled within a central opening within removable cover plate 62. The latter is retained on the end of housing 44 by screws 63, with a suitable gasket 64 being interposed between said plate and housing.

Hollow cylindrical cup valve 65 is rotatably journaled within mixing chamber housing 44, with its base portion centrally mounted on and secured to rotatable shaft 59.

Inlet opening 66 is formed in the side wall of cup valve 65 and is best illustrated in the diagram of Fig. 5. Said opening when in its upper vertical position is adapted for registry with the discharge opening of chute 43, permitting dry powdered or granular coffee to drop into the mixing chamber.

The cup valve also has a discharge opening 61 formed in its side wall which is adapted for registry with the opening in cofiee outlet 45. Hot

Said valve 69 is rotatably positioned within housing 44 with its flat inner surface in registry with the flat end wall of cup valve 65. Disc valve 69 is centrally mounted and secured upon the inner end of rotatable sleeve 6| which is rotatably journaled within cover 62 and upon rotatable shaft 59.

Spur gear H is secured and carried on the end of sleeve BI: and is at all times in mesh with corresponding manually rotated spur gear 57. Shaft 59 projects through sleeve 6| and extends beyond the end thereof carrying on its end sprocket gear 12, there being a washer l3 and gasket 14 mounted on said shaft and interposed between cent the central portion of said slot.

gears 12 and H.

- Sprocket gears 12 and 42 are interconnected by sprocket chain 15 and, as the former gear is half the size of the latter, is adapted to rotate twice as fast thereof for the purpose hereafter described.

Referring to Figs. 3 and 5 the central base portion of said cup valve has formed in its outer surface a 180 degree arcuate slot 16; and a water inlet jet 1! is threaded through said valve adja- Jet member 11 projects into the beverage mixing chamber within cup valve 64 and is adapted to direct hot or boiling water at relatively high velocity into direct impingement with the angular vanes 18.

Vanes 18 are centrally secured to hollow member 19 which is loosely and rotatably mounted upon shaft 59 within said cup valve.

Vanes 18 will thus rotate rapidly when impinged upon by water at relatively high velocity delivered I through jet 11, so that the coffee or other substance previously dropped into the mixing chamber will be thoroughly mixed and dissolved in the hot water.

The hot water heating unit consists of a hollow, cylindrical shell 841v which is positioned within the main container l l' and has a cover 81 Figs. 1 and 4. Hollow cylindrical insulating member 82 preferably constructed of asbestos is Dositioned within shell 88 adjacent its inner wall. Further there is a base insulating member 83 as well as a top insulating member 84 which is positioned within cover 81.

Hollow vapor exhaust pipe 85 threadably secured to cover 8|, and in communication with the interior of shell 80, extends upwardly projecting through a corresponding opening in container cover l3. Spiral water coil 86 having an inlet 81 is longitudinally positioned and supported within shell 86 with its outlet pipe 68 arranged to deliver hot or boiling water to the beverage mixing chamber within cup valve 65, above described.

Water supply pipe 88 on the outside of container ll, Figs. 1 and 2 is joined to coil inlet 8.! with hand valve 89 interposed. Coil 66 has a, secondary hot water outlet 96 at its lower end adapted to supply hot water to spigot 9|, Figs. 1 and 2 with hand control 92.

Hollow cylindrical member 93 carrying cylindrical insulating member 94 is longitudinally projected through the center of hot water coil 86 thereby providing an annular fully insulated chamber 95 therefor. A suitable electric heating coil 96 is positioned with chamber 95 with its elements arranged between the turns of hot water coil 86 throughout its length. The ends of heating coil 96 terminate in the hand switch 91 which is suitable joined to a source of electrical energy.
